Description for the above code

The above Python code will print the string "hello world" ten times. Here's a breakdown of how it works:

1. The for loop is set to iterate over the range from 1 to 10 inclusive. The range(1, 11) function generates a sequence of numbers starting from 1 up to (but not including) 11.

2. On each iteration of the loop, the print('hello world') statement is executed.

Because the loop iterates 10 times, "hello world" will be printed 10 times, each on a new line.

Here is the code:

for i in range(1, 11):
    print('hello world')

Output

hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world

Everyone Has a Story in Life

A 24 year old boy seeing out from the train’s window shouted…

“Dad, look the trees are going behind!”

Dad smiled and a young couple sitting nearby, looked at the 24 year old’s childish behavior with pity, suddenly he again exclaimed…

“Dad, look the clouds are running with us!”

The couple couldn’t resist and said to the old man…

“Why don’t you take your son to a good doctor?” The old man smiled and said…“I did and we are just coming from the hospital, my son was blind from birth, he just got his eyes today.”

Every single person on the planet has a story. Don’t judge people before you truly know them. The truth might surprise you.

መልካም ምሽት!

What is a While Loop?

የተወሰነ ሁኔታ እውነት እስከሆነ ድረስ በፓይዘን ውስጥ ለተወሰነ ጊዜ loop በተደጋጋሚ የኮድ እገዳን ይፈጽማል። ጥቅም ላይ የሚውለው የድግግሞሽ ብዛት አስቀድሞ በማይታወቅበት ጊዜ እና አንዳንድ ሁኔታዎች በሚሟሉበት ጊዜ ነው.

While loop በPython አንድን block of code specify የተደረገው condition እውነት እስከሆነ ድረስ repeatedly(በተደጋጋሚ) execute የሚያረግ የ Python flow control አይነት ነው። While loopን የምንጠቀመው number of iteration ለማይታወቅባቸው ወይም executionአቸው on some condition ላይ depend ለሚሆንባቸው blocks of code ነው።

Syntax of While Loop

የ While loop basic syntax ይሄንን ይመስላል:

while condition:
    # Code block to be executed

- condition: አንድ condition እውነት ወይም ሀሰት እንደሆነ evaluate የሚያረግ expression ነው።

- Code block: ይሄ ደግሞ specified የሆነው condition True በሆነ ቁጥር execute የሚደረግ የstatements ስብስብ ነው።

Flowchart of a While Loop

1. Evaluate the condition.
2. If the condition is true, execute the code block.
3. Re-evaluate the condition.
4. If the condition is still true, repeat the code block.
5. Continue until the condition becomes false.

...cont'd

ምሳሌ:
በዚህ ምሳሌ የምናየው program ከ 1 እስከ 5 ያሉ ቁጥሮችን print የሚያረግ ነው:

i = 1
while i <= 5:
    print(i)
    i += 1  # Increment the value of i by 1

Detailed Explanation

1. Initialization: i is initialized to 1 ማለትም i የሚባል variable initial valueውን አንድ አርገናል።

2. Condition Check: i <= 5 check ይደረጋል: conditionኡ እውነት ከሆነ loopኡ ይቀጥላል otherwise loopኡ terminate ያረጋል።

3. Body of Loop: print(i) የ variable 'i' ን current value print ያረጋል።

4. Increment: i is incremented by 1 using i += 1.
Increment ማለት የአንድን variable value በሆነ ያህል አማውንት መጨመር ማለት ነው፣ በላይኛው case each time the variable 'i' is being incremented by 1.

5. Re-evaluation: The condition i <= 5 is checked again with the new value of i.

Infinite Loop

While loopን ስንጠቀም common የሆነ ችግር ቢኖር የinfinite loop መፈጠር ነው። ይህም infinite loop conditionኡ False መቼም በማይሆንበት ጊዜ ይፈጠራል።


Example of an infinite loop:

while True:
    print("This will print forever")

ከላይ ያለው ፕሮግራም "This will print forever" የሚለውን ዐ/ነገር ያለ ገደብ print ያረጋል።


Breaking Out of a Loop

Infinite Loop avoid ለማረግ "break" statement መጠቀም እንችላለን፣ ይህም የሆነ condition set አርገን እውነት በሚሆንበት ጊዜ loopኡን exit እንድናረግ ይረዳናል።

i = 1
while i <= 10:
    print(i)
    if i == 5:
        break  # Exit the loop when i is 5
    i += 1

ከላይ ያለው ፕሮግራም መጀመሪያ የተፃፈው ከ 1 እስከ 10 ያሉ ቁጥሮችን print እንዲያረግ ቢሆንም የ'i' value 5 ሲሆን እንዲያቆም ቅድመ-ሁኔታ ስላስቀመጥን ልክ የ'i' value 5 ሲሆን loopኡ ይቆማል።


Using Else with While Loop

Python 'else' clause ከ while loop ጋር እንድንጠቀም ይፈቅዳል። የ'else' block executed የሚሆነው የ while loop condition ሀሰት ሲሆን ነው። (i.e., the loop terminates naturally).

ምሳሌ

i = 1
while i <= 5:
    print(i)
    i += 1
else:
    print("Loop has ended")

Common Use Cases

1. Waiting for User Input: የፈለግነውን data እስከምናገኝ User input በተደጋጋሚ እንድንቀበል ይረዳናል።


2. Processing Data Streams: መጨረሻ ላይ እስከምንደርስ data ከfile ወይም ከ network stream continuously እንድናነብ ይረዳናል።

3. Polling: የአንድን resource status periodically check እንድናረግ ይረዳናል።

ምሳሌ: User Input

Here's an example where we keep asking the user for a positive number:

number = -1
while number < 0:
    number = int(input("Enter a positive number: "))
print("You entered: ", number)

ከላይ ያለው ፕሮግራም userኡ positive ቁጥር እንዲያስገባ repeatedly ይጠይቀዋል፣ ቁጥሩን ደግሞ print ያረጋል፣ if the user enters a positive number the loop ends, because the condition becomes false.
